STAPLE-BINDING DELIVERY MECHANISMFOR PRlNTlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 510,843, dated. December 12, 1893.

Application filed August 16. 1893. Serial No. 483,240. (No model.)

To all whom it may concern.-

Be it known that I, LUTHER (lORoWELL, a citizen of the United States, residing at Brooklyn, county of Kings, and State of New York,

have invented certain new and useful Improvements in Staple-Binding Delivery Mechanism for Printing-Machines, fully described and representedin the following specification and the accompanying drawings, forming a to part of the same.

The improvements embraced in this invention are designed to form a part of the delivery apparatus of printing machines, whereby the printed product of such machines when consisting of plications may have the same united together by a stapled line of union as the binding line thereof. These improvements are embodied in that class of stapling mechanisms which travel rotatively during I the operation of carrying and presenting the staple into position relative to the material for its insert-ion therein, whereby they are especially adapted to operate in connection with printing machines of the rotating type or other 2 5 machines that rapidly produce plicated sheets or webs, being thus capacitated to bind the same by means of staples set in, on or along the ultimate binding line thereof so as to produce a bound book-like product at a high rate of speed and without modifying the rapidity of the printing or other operation performed upon the material, as is set forth in my application, Serial No. 464,007, filed February 28, 1893. In its broad scope the presentinvention in cludes a rotating carrier by which the'staple holder or presenting tool of the staple inserting means is moved to and from the inserting and setting points, in which carrier is sup- 0 ported rotative staple forming devices operating to supply staples to said holder or presenting tool for insertion into the material.

The invention includes in combination therewith means for feeding the material to be stapled onward past the staple inserting means, and a co-operating means for feeding wire and cutting staple lengths therefrom, means for transferring the staple from its forming devices to the holder or presenting 5o tool, means forinserting the staple, and means for clinching its legs; and the invention also embraces rotative staple forming devices.

The foregoing comprehensively states the object of and principal features of the invention, but many combinations and constructions of instrumentalities and mechanisms are embraced in the invention, as will be so fully hereinafter set forth and claimed.

Practical embodiments of these improvements are illustrated in the accompanying 6o drawings, and in these drawings, section lines mark the plane in which an illustration is made, the reference number for the line indicates the figure which embodies theview, and the arrow head connected with each section line points the direction in which the picture is seen. I

Feathered arrows show the direction of movement of the parts with which each is associated, and like reference characters desig- 7o nate corresponding parts.

Fig. 12 is a like partial view of the staple holding or presenting tool and driver or inserting tool. Fig. 13 is a rear view of the outer end of the operating lever for the staple holder or presenting tool and driver or inserting tool. Figs. 14, 15, and 16 are sectional elevations taken respectively on the lines 14:, 15 and 16 of Fig. 6.

To readily understand these improvements it should first be stated that the same are for convenience, illustrated as forming a part of the delivery apparatus of printing machines whereby the printed material is discharged from the machine in sheet form ready for use. By the use of these improvements the sheets are bound together by means of small wire staples set in, on or along the binding line so as to constitute the product of the machine a book-like package.

The improvements are applicable to all machines which are capable of producing a plicated product, whether the same consists of sheets or webs. There are many such machines which substantially embody multiplex printing mechanisms operating upon two or more sheets or webs and provided with means for bringing two or more sheets or webs into association for delivery as one product, or operating upon wide sheets or webs have means for dividing them longitudinally one or more times, and associating the divided parts, or of folding said sheets or webs so as to form a plicated product. Preferably these improvements will be applied to that type of printing machines which operate upon webs of paper and embody a longitudinal folder or folders as a part of the delivery apparatus, whereby the webs are plicated, but this plication may be accomplished by associating bars or rollers, and may be performed upon sheets if a cutting apparatus is provided to transversely sever the webs before the longitudinal folders are reached, in which case, as is well understood, a taped or equivalent pathway will be used to cause the sheets to move regularly onward until mechanisms are reached which will carry them without the aid of such pathway; and although one 1ongitudinal folder may be used for the reception of many webs, I have illustrated herein two such longitudinal folders to indicate that this invention may be arranged to operate upon webs or sheets received from independent printing machines, or split webs from suitable printing forms, by using one or more longitudinal folders, as may be desired. These longitudinal folders L, may be of any construction, but preferably will be made substantially as is set forth in Patent No. 331,280, dated February 8, 1884. They are shown as provided with external turners 63, 64 and with folding laying rollers 65, 66. Each is exhibited as acting upon four webs as M, A, N, Y and W, E, B, S, and as a means for associating part or all of the webs from each of these folders, associating rollers 67, 68 are shown as mounted to turn just above the carriers 0, D, that support the stapling mechanisms. These carriers 0, D, are shown as cylinders, but that construction of them is not essential since as mere rotative carriers for the tools they need not provide any peripheral surface but only provide a support that will insure the rotative movement of the tools, however, as it is desirable that the material operated upon, shall at the time of the performance of the stapling operation provide a support for the material contiguous to the tools the cylindrical form is preferred; moreover, such cylinders may operate to feed the material or one of them carry pins to perform that oilice, and the other may form an inclosure for some of the tools, and such structure therefore presents advantages over one operating merely as a carrier for the tools. These rollers 67, 68 (the latter spring seated) will be geared together and are shown as geared to and driven by a wheel 75 on the shaft of cylinder D through an intermediate 76. They thus be come the drawing rollers for advancing the material,but the rollers 65, 66 may have companion rollers, the pairs so constituted being driven to act as driving rollers.

While it is not essential, although desirable, the cylinder 0 is provided with a cutting blade 28, and the cylinder D with a cutting slot 29 for the transverse severance of the material into sheet lengths, and the cylinder D is also provided with a rotative folding blade 71 for co-operation with folding rollers 72, 73 for folding the stapled bound product; but these cutting and folding devices might be supported in carriers independent of the cylinders O, D, if desired, all as is set forth in my applications, Serial Nos. 483,191 and $3,192, both filed August 15, 1893.

The staple forming, holding or presenting, and driving or inserting mechanisms or tools are carried by and preferably within a rotative carrier (1, which may be a cylinder, they being in part supported and operated by a longitudinal shaft 90 that is journaled in the heads of and near the periphery of the cylinder 0 and in part supported by housings 1-1 that are inserted in recesses of proper size cut into the cylinder, and they are in part enibraced within recessed portions of said shaft 90. These housings are secured in place by screws so that their outer facial surface forms a continuation of the peripheral surface of the cylinder C, see Figs. 4 and 9, and they provide a guideway for the holder or presenting tool and the inserting tool or driver.

The shaft 90 is provided with a driving wheel 91 fast upon one of its ends, which wheel 91 meshes with a toothed ring 92 that surrounds the shaft 59 of the carrier 0 and is fixed to the side frame of the machine, from which it results that as said shaft 90 is carried around with the cylinder, the said gearing will impart to it said shaft the requisite rotary motion to properly operate the mechanisms it actuates.

There will be as many sets of staple form ICC ing,hol'der or presenting, and driver or inserting mechanisms, tools or devices as may be desired, according to the width of the material to be operated upon, three being shown in Fig. 2 as sufiiciently illustrative; and these, or some of them, may be made adjustable with respect to others so that the distance between the stapling points or between adjacent staples may be varied.

A description of the construction, arrangement and operation of one set of these stapling mechanisms will now be given, it being understood that the several sets are all alike. pling mechanisms carries a circular die consisting of an outer section 80, an inner sec tion 16 and two side sections 81, 82 between which is provided a curved pathway for the guidance of the staple. One side section 82 has a wire feeding slot 3, and a wire receiving recess 1 and the side section 81 has extending partially through it a wire receiving recess 9 which recesses are thus separated and made long enough to limit the entrance ofthe wire to an extent just equal to the length required to formra staple. The inner portions of the side sections 81, 82 where the wire receiving recesses 1, 9 cut the same constitute stationary staple leg bending arms 25, 26, which operate to turn or bend the ends of the wire length at right angles to the body portion as the rotating bender carries the body portion onward, and the section 82 is provided circumferentially with a recess 32 that provides a circular pathway in which travels a rotary wire cutter 33 that is fast on the shaft 90. Each stapling mechanism also has a rotary staple bending anvil, shown as consisting of two rings (Figs. 6 and 15) that are fast upon the shaft 90 and which are respectively provided with bearing arms 10, l1,which anvil arms move on opposite sides of the inner section 16 of the circular die (see Fig. 11) that embraces but does not move with the shaft 90, the same being secured rigidly in place by means of aback strap 62 secured to the housing H, see Fig. 16. These anvil arms 10, 11 are thus held apart a distance equal to the length of the staple to be formed and they project outward a distance about equal to the thickness of the wire from which the staple is to be formed. The side sections 81, 82 of the circular die have cut into their inner side faces,curved recesses that face each other and in which are secured cheek pieces 30, 31 that project.

The housing for each of these stamess that provides betweenits inner face and the outer face of the inner section 16 a curved guiding recess or pathway for the crown of the staple that is suited to the size of the wire used. The outer or bearing face of the inner section 16 and the co-operating inner face of Y and the cheek pieces 30, 31, are of corresponding form, see Fig. 14, so that while the arms 10, 11 of the rotary bender force the formed staple onward, the increasing-arc of its pathway formed by the cheek pieces 30, 31 or the inner section 16 constitute an elevator that will carry it into the open endof said holder or presenting tool.

The staple receiving, presenting tool or holder and the inserting or setting tool or driver, both reciprocate in a right line in a recess or guiding way out through the housing H, the same being partly formed -.in the side sections 81, 82 and covered by a central removable cap piece 70. See Figs. 4, 5 and 10.

The staple presenting tool or holder consists of a head having bearers, 22, 23, curved to fit the correspondingly shaped bearings formed in the side sections 82, 81, and from opposite sides of this head there are forwardly projecting arms 20, 21, that have their inner faces recessed to provide a channel way to receive the formed staple, and these recesses each have one side wall, that which is nearest to the staple forming devices curved, as at 6, to form, when the arms are retracted to their rearward positions, as in Fig. 4, continuations of the inner surface of the eccentric guide or pathway formed between the faces of the outer section and the cheek pieces 30, 31; and the body of the presentingtool or holder has curved recesses 38, 39 cut in its face to provide for the unobstructed movement of the anvil arms 10, 11 past it. By this construction the formed staple carried through the curved pathway by theanvil .arms 10, 11 of the rotary anvil will be raised to clear said arms by the inner section 16 or the cheek pieces 30, 31, acting as an elevator, and be landed in the channel way within these arms 20, 21, of the holder orpresenting rock shaft 42 in the slotted free end of which lever the shank 43 of the driver 2 is pivoted,

see Figs. 12 and 13, and this shaft 2, which is journaled in the heads of the cylinder 0', is.

appropriately rocked at suitable intervals by means of a rock arm 44 on its outer end, the stud or friction bowl of which runs on a cam 45 that is secured to the fixed wheel 92.

The staple presenting tool or holder which has the arms 20, 21 is attached to the lever 41 by means of two rods 46, 47 that play in cars 48, 49 projecting from the sides of the free end of said lever, its position with respect to that lever being secured by means of spiral springs that encircle said rods and hear at one end against the rear of the head of the said instrument and at the other against said ears.

The rotary wire cutter 33 is carried by a ring 34 which is fast upon the shaft 90, and said cutter 33 projects sufficiently to cause itto intercept, at right angles thereto, the plane of the transverse wire passage 3 in the side section 82 and the arm 20 of the staple holder or presenting tool is also recessed as at 18 to provideaclearance for said cutter. The staple length of wire enters through the passage 3, extends past the cutter 33 and entering into the wire slots 1, 9, reaches across the guideways in which said cutter and the arms 10, 11 of the rotary anvil move, and has its leading end abutted against the inner end of the wire passage 3, and thus portions of the wire length are provided each side of said anvilsufticient forthe formation of the staple legs; and, in its rotative travel this cutter 33 co-operates with the side wall of the recess 32 where the wire passage 3 joins it to perform the cutting operation and sever a staple length.

The wire 17 from which the staples are to be formed is wound upon spools 12, 13, 14 supported upon one head of the cylinder 0, there being as many spools as there are staple forming mechanisms employed. The spools are j on rnaled in brackets and the wires from them are led about feeding rollers whose shafts are rotated by a train of gears 50, 51, 52, 53, the shaft of the latter having at its opposite end a worm wheel 54 engaged with a worm 55 that is on a shaft which is geared by pinions 5G, 57 with a toothed wheel 58 encircling the shaft 59 of the cylinder 0 and fast to the frame work, by which gearing said roller shafts are continuously and con certedly moved. As the wires must be brought into the same plane or common feeding line, the wires from all the spools are passed between guide rollers 4, 5, thence between rollers 5, 7, and thence between guiding rollers 7, 8, so that the three wires enter the cylinder in a common plane, see Fig. 2, where the gears 50, 51, 52 and 53 are omitted so as to expose the rollers 4, 5, 7, 8, which are shown in clotted lines.

Within the cylinder 0 there is provided a wire guide plate P in which are grooves 35, 36, 37 that so guide and direct the wires that they all enter and are presented to the wire passages and cutters of the several staple forming mechanisms at points correspondingly related to each. See Fig. 3.

It being understood that the cylinders C, D are geared and driven so as to revolve in unison with the other moving parts with which the material must concertedly run, that the cylinder 0 carries a number of staple forming holding or presenting, and inserting mechanisms or tools aligned longitudinally in the said cylinder, and that the circumference of the cylinder is equal. to the length of a sheet, and that the cylinder D is provided with as many co-operating staple leg clinching devices as there are stapling presenting mechanisms, which clinching devices may be the shallow channels or grooves 15 with curved ends, as shown, the operation will be as followsz-The plicated material from one or both of the longitudinal folders will be fed onward between the carriers or cylinders C, D,suitable staple lengths of the wires 6 will be fed to the mechanisms carried by the cylinder 0 and the wire cutting, staple forming, presenting and insertin g mechanisms, will progressively act as follows:-Thewire will be fed through the slot or channel 3 and into the wire recesses 1, 9, to a proper extent or until it is stopped by abutting against the inner end of the recess 9, whereupon a staple length of it will be cut off by the action of the rotary cutter 33. This severed wire or detached staple length will immediately be intercepted or caught by the arms 10, 11 of the rotary anvil and its central body or crown portion will be carried into the guideway between the side sections 81, 82, the arms 10,,11 of said anvil, the inner face of the central section 80, and the outer face of the curved central guide 16, while its projecting ends or leg portions will be forced against and turned over the slightly curved corners of the bending arms 25, 26, which form the junctions between the wire recesses 1, 9 and such guideway. As the wire length is thus carried forward by the rotary anvil its ends or leg portions will be turned rearward by the bending arms so as to be at right angles to its body or crown, see Figs. 7 and 8, thus providing it with legs and completing the staple. This staple thus completely formed will be carried onward by the arms of the rotary anvil and will be progressively moved outward bodily and finally following the eccentric guideway, be swept into the embrace of the arms 20, 21 of the holder or presenting tool by the elevating action of the cheek pieces 30, 31 or the inner section 16, or both as the case may be, the staple being thus gradually withdrawn from contact with the arms 10, 11 of the rotary anvil, which arms pass onward in their circular travel through the recesses 38, 39. The formed staple will then rest in the holder or presenting tool with its legs embraced in the arms 20, 21 and pointing outward with its crown resting in front of and against the face of the driver 2. At the proper time while the carrier 0 is moving onward this holder or presenting tool or instrument Wlll be moved outward by the action of cam 45 and be protruded beyond the periphery of the cyllnder or carrier 0 as in Figs. 1 and 5, and reach this position while that part of the cylinder or carrier C which carries the presenting tool or holder is approaching the settlngpoint, which is Where the cylinders O, D roll in or nearly in contact, in which position of the holder or presenting too], its arms 20, 2]. W111 support the staple outside of the cylinder as shown in Fig. 1. When this holder or presenting tool, in its circular path of travel, meets the material passing between the cylinders O, D, it will cause the staple held therein to enter the material and be progresslvely inserted therein, as the said cylinders roll onward, contact of the cylinder D, or the staple leg clinching device, with these arms 20, 21 causing their retiring movement against the resistance of the springs on the rods 46, 47, while the cam 45 holds the driver 2 rigidly until the staple legs are bent or clinched by the action of the clinching grooves 15 1n the surface of the cylinderD. It has been sa1d that the cheek pieces 30, 31, or the inner sections 16 will act as an elevator lifting the formed staple out of contact with the anvil arms 10, 11, so as to land or deposit the formed staple within the arms of the holder or presenting tool in advance of the driver or insertlng tool 2. From slight consideration, it Wlll be seen that the cheek pieces bear against the staple legs, and obviously they may consequently alone act upon the staple to lift it since the staple crown must follow its legs; and likewise if the inner section 16, upon which the crown of the staple bears, is alone used as the elevator the legs of the staple WIII fOllOW the crown of the holder or presenting tool, being partially aided by the centrifugal action due to the high speed at which the mechanism will run; and, if the cheek p eces are depended upon as the elevator it will further be apparent that the anvil arms 10, 11 may be connected so as to constitute the anvil a single piece having a continuous face bearing against the staple crown. The wlres are shown as fed inward and cut ofi to suitable staple lengths. This is desirable, but prev ously prepared lengths might be suitably fed to the rotating die and the cutter 33 dispensed with.

It is to be observed that the staple inserting means consists generally of a staple holder or presenting tool which receives and holds or presents the staple so that its legs shall properly enter the material, and a tool or driver which acts to compel the entrance of the staple into the material. It is to be understood, however, that the staple holding or presenting tool may also act as a tool or driver for inserting the staple into the material, and that it need not in some constructions be protruded beyond the periphery of the cylinder or carrier, but act to so protrude the staple; also that the operation of so protruding the staple and accomplishing its insertion may be effected when the staple inserting position has been reached.
